VALVE-POSITION CONTROLLING AND' INDICATOR DEVICE.

To all whom it may concern:

Be it known that I, FREDERICK N. CON- NET, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in tion is to provide a simple means for indicat-- ing the position of the said main valve or the amount of opening in the same.

My im roved device is more particularly adapted or use on an operating table in filtrat-ion plants vhere an indicating device of this character is required to be both efiicient in its operation, simple in construction and neat in its appearance, and to this end I employ an upright tubular stem extendin through the top of the table to the upper en of which stem 15 secured an operating handle while the lower end is operatively connected to an auxiliary valve, whereby the movement of said handle actuates 'said valve to cause said main valve to be operated by water pressure.

An essential feature of my invention is that a gage spindle is held within the tubular stem and is arranged to be moved vertically therein by the movement of the main valve and in proportion to said movement so that the amount projecting above said stem in ivalve.

The invention is fully set forth in this specification and more particularly pointed out in the appended claims.

, In the accompanying drawings: Figure 1 is a side elevation of my device art-1y in section showing the same operative y connected to control the action of a hydrau ically operated valve, and also showing the indicator operating means.

I Patented Sept. 22, 1908.

Referring to the drawin s, at 1 is the main ipe in which is located the main valve 2. T 's valve is shown partly in'section and in a conventional form, the gate being represented at 3 and the stem 4 extending up into a cylinder 5 and is attached to the piston 6 which piston is adapted to be moved either up or down in said cylinder by a water pressure entering through the pipes 7 or 8, each of which pipes serves in a double capacity which is to conduct either the pressure or the exhaust according to the direction of movement required of the piston. The

upper ends of these pipes 7 and communicate through the ports 9 and 10 with the auxiliary valve chamber 11 mounted on the rail 17. Also communicating with this chamber 11 are the exhaust and pressureports 12.nnd 13 which ports also connect with the mam conducting apertures or passageways 15 and 1 16 located in said rail 17. A D-sha-ped auxiliary slide valve 14 is adapted to be moved so as to admit the pressure from port 13 into either of )ipes 7 or 8 and at the same time connect t e opposite pipe with the exhaust port 12. The collar 18 is mounted on the operating table 19, the hollow neck of said collar 20 passin through the hole 21 in the table and the t readed nut 22 secures the same in place. Passing through this collar and neck is the hollow valve stem or shaft 23 to the upper end of which is secured the operatin handle 24 by its hub 25. The lower end 0 this stem is reduced at- 26 forming a portion of small diameter that projects down through the stulling box 27 in the upper part of the valve chamber 11, and on its i end is fixed alever 28, the outer end 29 of which engages a recess 30 in the valve 14 so that when the operating handle 24 is moved either to the right or to the left the valve 14 receives a corresponding motion. In order to lock this stem in any desired position and prevcntthe same from being inadvertently moved I have provided a cam 31 mounted on the shaft 32 to be actuated bymeans of V 1 center portion more closely, but also adapted 0 hollow stem or shalt vertically therein is the gage spindle the handle 33-so that when said handle is turned down into the position shown in Fig.

. 1 the said cam engages the collar 34 fixed to said stem and binds and holds the same se- Located within this and adapted to slide curely from movin which is graduated at its upper end. To the lower end of this spindle is fixed an enlarged portion 36 designed to fit the hollow to move freely therein. To this enlarged portion is fixed a finger or pin 37 which extends out through the slot 38 formed throiwh the wall of the tubular stem. The idl er pulle 39 is sup orted on the bracket 40 whic bracket is ound and held by the nut 22 against the underside of the table 19.

'The cord 41 leads from the pin 37 over said dle 48. This spindle 48' extends down sive in construction, is easy to mani through thecylinder head and is attached to the piston 6 within. The movement of this iston either up or down through the sproc et chain and connections described rotates the sprocket wheel 44, the rotation of which sprocket also rotates the drum 42 on which is wound the cord 41. The movement of this drum therefore in one direction winds the cord 41 around the same drawing u ward the gage spindle to extend above t e upper en of the tubular stern, while an o posite movement of said drum unwinds t e cord therefrom and allows said spindle to drop downward into said stem, the amount of said spindle projecting above said stem indicating the amount of opening of the main valve.

The apparatus is very simple and inezqienu ate and eifective in its operation, and by its use the main valve may be easily operated and the position of the valve gate readily determmed by a glance at the indicator which 7 is always in plain sight.

Having thus described my invention, what- I claini as new and desire to secure by Let-' ters Patent, is:
